A young woman found dead in an Iowa cornfield, on one of the few family farms still managing to compete with the giants of Big Agriculture. For Sergeant Riley Fisher, newly promoted to head of investigations at the Black Hawk County Sheriff's Office, an already horrific crime takes on a personal edge when she discovers the victim is an old friend, from a dark past she thought she'd left behind. Rumour travels fast in small towns, while sweltering heat and state-wide elections only add to the pressure-cooker atmosphere. When another body is found, Riley is in danger of being engulfed by the fear and the frenzy. Something deeply disturbing is out there - and it reaches far beyond Black Hawk County.
